Detailed Implementation

[0055] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0056] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0057] Currently, to meet customers' sunshade needs, most automobiles use electric sunshades, which, in conjunction with the sunroof, provide sun protection and heat insulation. Existing sunshades are generally divided into direct-drive and non-direct-drive types. Direct-drive sunshades typically use an L-shaped motor with worm gear drive, which drives a pulley or synchronous belt pulley at the sunshade roller end. The movement of the steel wire or synchronous belt then moves the sunshade forward and backward, achieving system transmission and control of the sunshade's opening and closing.

[0058] In this design, the L-shaped motor outputs torque through a worm gear reducer, which is then transmitted to a synchronizing pulley or spool, enabling the entire system's wheel assembly to rotate. However, due to design limitations, the L-shaped motor requires significant space in both the width and length directions of the vehicle. Furthermore, the large space occupied by the worm gear reducer affects the arrangement of the body panels. The motor's extended cantilever is relatively long, causing swaying under load and potentially generating vibration and abnormal noise. Additionally, the L-shaped motor cannot be used on both sides; if shared, it must be rotated 180°, further increasing its space requirement within the vehicle.

[0059] In view of this, and to solve the above problems, please refer to Figures 1-4. This application provides a sunshade assembly 1, which includes a sunshade 10, a retractable assembly 20, and a drive assembly 30. The retractable assembly 20 includes a first rotating wheel 21 and a transmission component. The first rotating wheel 21 is rotatably connected to the transmission component, and the transmission component is connected to the sunshade 10. The drive assembly 30 includes a reducer 31 and a motor 32. The motor 32 drives the reducer 31 to rotate. The central axis of the reducer 31 coincides with the central axis of the motor 32, and the central axis of the reducer 31 is perpendicular to the length direction of the transmission component. The first rotating wheel 21 is sleeved on and connected to the reducer 31. The motor 32 can drive the transmission component to rotate sequentially through the reducer 31 and the first rotating wheel 21, thereby driving the sunshade 10 to move.

[0060] The sunshade assembly 1 provided in this application can be applied to multiple fields. This application is only used to illustrate the application of the sunshade assembly 1 in vehicles, and does not mean that the sunshade assembly 1 can only be used in the vehicle field. For example, the sunshade assembly 1 can also be used in the construction field, home field, industrial field, etc.

[0061] The sunshade 10 includes a curtain body 102 and a pull rod 101. The curtain body 102 is connected to the pull rod 101 and is used for shading. The pull rod 101 is connected to a transmission component. The transmission component can drive the pull rod 101 to move, thereby driving the curtain body 102 to move. The direction of movement of the sunshade 10 is shown as D1 in Figure 3. When the sunshade assembly 1 is applied to a vehicle, the sunshade assembly 1 is fixed to the glass, and the sunshade 10 is set corresponding to the glass. The glass can be installed in any position on the vehicle and can be used for, for example, sunroof glass, windshield glass, rear window glass, and side window glass. The glass is preferably sunroof glass. The sunshade 10 can be used for sun shading or projection, improving the user experience.

[0062] The winding assembly 20 connects the sunshade curtain 10 to the drive assembly 30. The drive assembly 30 drives the sunshade curtain 10 to move via the winding assembly 20, thereby achieving the winding of the sunshade curtain 10. The winding assembly 20 includes a first rotating wheel 21 and a transmission component. The first rotating wheel 21 is rotatable. The first rotating wheel 21 is rotatably connected to the transmission component; for example, the first rotating wheel 21 is directly rotatably connected to the transmission component; or, the first rotating wheel 21 is indirectly rotatably connected to the transmission component through other components. Optionally, the transmission component can be a synchronous belt 22 or a steel wire. Optionally, when the transmission component includes a synchronous belt 22, the first rotating wheel 21 has a ring of external teeth, the synchronous belt 22 is sleeved on the first rotating wheel 21, and the synchronous belt 22 has a ring of internal teeth, the internal teeth of the synchronous belt 22 meshing with the external teeth of the first rotating wheel 21. The first rotating wheel 21 is connected to a reducer 31, wherein the connection method between the first rotating wheel 21 and the reducer 31 can be adhesive connection, threaded connection, snap-fit, etc., which is not limited in this embodiment.

[0063] The drive assembly 30 is used to drive the winding assembly 20. The drive assembly 30 includes a motor 32 and a reducer 31. The motor 32 and the reducer 31 are rotatably connected, and the motor 32 can drive the reducer 31 to rotate. For example, the motor 32 is directly connected to the reducer 31; or, the motor 32 is indirectly connected to the reducer 31 through other components. The central axis of the reducer 31 coincides with the central axis of the motor 32, which can also be understood as the reducer 31 and the motor 32 being coaxially arranged. The central axis of the reducer 31 is perpendicular to the length direction of the transmission component, which can also be understood as the arrangement direction of the reducer 31 and the motor 32 being perpendicular to the length direction of the transmission component, the arrangement direction of the reducer 31 and the motor 32 being perpendicular to the thickness direction of the transmission component, and the arrangement direction of the reducer 31 and the motor 32 being the same as the width direction of the transmission component. The rotation direction of the reducer 31 is shown as D2 in Figures 3 and 4.

[0064] Among them, motor 32 can be a frameless torque motor. Frameless torque motors lack a traditional housing (frame) and bearings, typically consisting of only two main parts: a rotor and a stator. Frameless torque motors can be directly embedded in the bracket 51 of this application, featuring a hollow design for easy wiring, achieving high integration, and thus reducing the size of the final product. Furthermore, frameless torque motors offer advantages such as high torque, stable performance, and high precision. Reducer 31 can be a planetary reducer. A planetary reducer typically consists of a sun gear (central gear), multiple planet gears, and an internal gear ring. The planet gears rotate around the sun gear (revolution) and also rotate around their own axes (rotation). Planetary reducers can achieve a large reduction ratio within a small volume and provide high torque output, offering advantages such as high efficiency, high torque, and compactness.

[0065] Specifically, the motor 32 drives the reducer 31 to rotate. Then, the reducer 31 drives the first rotating wheel 21 to rotate. Subsequently, the first rotating wheel 21 drives the transmission component to rotate. The transmission component then drives the sunshade 10 to move, thereby controlling the opening and closing of the sunshade 10.

[0066] In the drive assembly 30, the central axes of the reducer 31 and the motor 32 are aligned, allowing the drive assembly 30 to occupy only one direction of the vehicle's space. This smaller footprint and reduced volume further facilitate the placement of other components, providing a wider field of vision for the vehicle's panoramic sunroof and more space for the body panels. Furthermore, the coaxial arrangement of the motor 32 and reducer 31, without cantilever, results in greater stability and less wobbling during operation, reducing the risk of vibration and abnormal noise. Additionally, the axial connection and central symmetry between the motor 32 and reducer 31 allow for left-right sharing.

[0067] By adopting the sunshade assembly 1 provided in this embodiment, the overall size of the sunshade 10 is reduced while ensuring a stable torque output of the motor 32, thereby reducing the space occupied by the sunshade 10 and significantly improving the vehicle's field of vision.

[0068] Please refer to Figures 1-6. In one embodiment, the inner circumference of the first rotating wheel 21 is provided with a first connecting part 211, and the outer circumference of the reducer 31 is provided with a second connecting part 313 that cooperates with the first connecting part 211. The first connecting part 211 and the second connecting part 313 are connected.

[0069] Furthermore, the first connecting part 211 is used to engage the second connecting part 313 so that the first rotating wheel 21 is engaged with the reducer 31.

[0070] The outer circumference of the first rotating wheel 21 is provided with external teeth for rotatable connection with the timing belt 22. The inner circumference of the first rotating wheel 21 is provided with a first connecting portion 211, and the number of first connecting portions 211 can be one or more. Optionally, when there are multiple first connecting portions 211, the multiple first connecting portions 211 are spaced apart along the circumferential direction of the first rotating wheel 21. Optionally, the distance between two adjacent first connecting portions 211 is equal.

[0071] The reducer 31 has a second connecting portion 313 on its outer periphery, and the number of second connecting portions 313 is one or more. Optionally, when there are multiple second connecting portions 313, the multiple second connecting portions 313 are spaced apart along the circumferential direction of the reducer 31. Optionally, the distance between two adjacent second connecting portions 313 is equal. Optionally, the number of first connecting portions 211 is equal to the number of second connecting portions 313.

[0072] When the first connecting part 211 is connected to the second connecting part 313, the first connecting part 211 abuts against the second connecting part 313, so that the first rotating wheel 21 is fixed on the reducer 31. The connection method between the first connecting part 211 and the second connecting part 313 can be a ring snap connection, a cantilever snap connection, a torsion snap connection, a U-shaped snap connection, an interference fit connection, a welding connection, etc., and this embodiment does not limit it.

[0073] In summary, by providing the first connecting part 211 and the second connecting part 313, this embodiment connects the first rotating wheel 21 to the reducer 31, which not only improves the connection performance between the first rotating wheel 21 and the reducer 31 and enhances the working stability of the sunshade assembly 1, but also facilitates the disassembly and assembly of the first rotating wheel 21 and the reducer 31, thereby reducing installation and maintenance costs.

[0074] In one embodiment, one of the first connecting portion 211 and the second connecting portion 313 is a snap-fit ​​protrusion, and the other of the first connecting portion 211 and the second connecting portion 313 is a snap-fit ​​groove, the snap-fit ​​groove being used to accommodate at least a portion of the snap-fit ​​protrusion.

[0075] For example, the first connecting portion 211 is a snap-fit ​​protrusion, and the second connecting portion 313 is a snap-fit ​​groove; or, the first connecting portion 211 is a snap-fit ​​groove, and the second connecting portion 313 is a snap-fit ​​protrusion. Optionally, the shapes of the snap-fit ​​protrusion and the snap-fit ​​groove are matched; for example, the snap-fit ​​protrusion is a rectangular protrusion, and the snap-fit ​​groove is a rectangular groove. When at least a portion of the snap-fit ​​protrusion is disposed within the snap-fit ​​groove, the snap-fit ​​protrusion abuts against the snap-fit ​​groove.

[0076] In summary, this embodiment, by setting the snap-fit ​​protrusion and snap-fit ​​groove, is simple to operate and has low manufacturing cost, and can fix the first rotating wheel 21 onto the reducer 31.

[0077] Please refer to Figures 5-7. In one embodiment, as shown in Figures 5 and 6, the first rotating wheel 21 is connected to the reducer 31 by a fastener thread. Alternatively, the first rotating wheel 21 is bonded to the reducer 31. Or, as shown in Figure 7, the first rotating wheel 21 and the reducer 31 are integrally formed structural components.

[0078] For example, the first rotating wheel 21 is provided with a first through hole 212, and the reducer 31 is provided with a second through hole 314. The first through hole 212 and the second through hole 314 are used to accommodate fasteners, which can be screws, studs, bolts, etc. Optionally, the first through hole 212 is provided in the first connecting part 211, and the second through hole 314 is provided in the second connecting part 313.

[0079] Alternatively, for example, the first rotating wheel 21 is bonded to the reducer 31 by an adhesive.

[0080] Alternatively, for example, the first rotating wheel 21 can be integrally formed with the reducer 31 using injection molding. Specifically, the first rotating wheel 21 is formed on the outer periphery of the reducer 31 by injection molding.

[0081] In summary, this embodiment uses threaded connection, adhesive connection, or forming an integral structural component to connect the first rotating wheel 21 and the reducer 31, which not only improves the connection performance between the first rotating wheel 21 and the reducer 31, but also has the advantages of simple operation and low manufacturing cost.

[0082] In another embodiment, after the first rotating wheel 21 is engaged with the reducer 31, the first rotating wheel 21 is then threadedly connected to the reducer 31, further securing the first rotating wheel 21 firmly to the reducer 31, improving the connection performance between the first rotating wheel 21 and the reducer 31, thereby further improving the working stability of the sunshade assembly 1.

[0083] Please refer to Figures 1-9 together. In one embodiment, the winding assembly 20 further includes a support member 23 for winding up the sunshade 10, and the support member 23 is connected to the reducer 31.

[0084] Furthermore, the reducer 31 includes a first mounting portion 311 and a second mounting portion 312. The first mounting portion 311 is closer to the motor 32 than the second mounting portion 312. The first rotating wheel 21 is connected to the first mounting portion 311, and the end of the support member 23 is connected to the second mounting portion 312.

[0085] The winding assembly 20 also includes a support member 23, to which the curtain body 102 of the sunshade 10 is connected and wound. The support member 23 is used to wind up the curtain body 102 of the sunshade 10. The support member 23 can also be understood as a support rod. One end of the support member 23 is connected to the second mounting part 312 of the reducer 31. For example, the support member 23 is directly connected to the second mounting part 312; or, the support member 23 is indirectly connected to the second mounting part 312 through other components. When the reducer 31 rotates, the support member 23 also rotates synchronously.

[0086] The reducer 31 includes a first mounting portion 311 and a second mounting portion 312, which are arranged along the axial direction of the reducer 31. Optionally, the radial dimension of the first mounting portion 311 is larger than the radial dimension of the second mounting portion 312. The first mounting portion 311 is connected to the second mounting portion 312; for example, the first mounting portion 311 is directly connected to the second mounting portion 312, or the first mounting portion 311 is indirectly connected to the second mounting portion 312. A first rotating wheel 21 is sleeved on and connected to the first mounting portion 311, and a support member 23 is connected to the second mounting portion 312. Optionally, the support member 23 is connected to the surface of the second mounting portion 312 facing away from the first mounting portion 311. Optionally, the support member 23 is inserted into the second mounting portion 312; or, the support member 23 is sleeved on the second mounting portion 312.

[0087] Specifically, the reducer 31 drives the first rotating wheel 21 and the synchronous belt 22 to rotate in sequence, thereby driving the pull rod 101 and the curtain body 102 of the sunshade curtain 10 to move. At the same time, the reducer 31 also drives the support member 23 to rotate, so that the support member 23 synchronously rolls up the curtain body 102 of the sunshade curtain 10.

[0088] In summary, this embodiment connects the support member 23 to the second mounting part 312 and the first rotating wheel 21 to the first mounting part 311, thereby using a single drive assembly 30 to realize the movement and retraction of the sunshade 10. This simplifies the structure, improves the integration of the sunshade assembly 1, further reduces the space occupied, facilitates the installation of other components, makes the vehicle sunroof more open, and provides more space for the body sheet metal.

[0089] Please refer to Figures 8 and 9 together. In one embodiment, the end of the support member 23 is inserted into the second mounting portion 312; or, the end of the support member 23 is sleeved on the second mounting portion 312.

[0090] For example, the second mounting portion 312 has a first mounting hole on its surface opposite to the first mounting portion 311, and the end of the support member 23 is disposed in the first mounting hole. In this case, the end of the support member 23 is inserted into the second mounting portion 312.

[0091] For example, the end of the support member 23 is provided with a second mounting hole, and the second mounting part 312 is provided in the second mounting hole. In this case, the end of the support member 23 is sleeved on the second mounting part 312.

[0092] The support member 23 is provided with a third connecting part 231 at its end, and the second mounting part 312 is provided with a fourth connecting part 315 that cooperates with the third connecting part 231. The third connecting part 231 is connected to the fourth connecting part 315.

[0093] Furthermore, the third connecting part 231 is used to engage the fourth connecting part 315 so that the support member 23 is engaged with the second mounting part 312.

[0094] For example, when the second mounting part 312 is provided with a first mounting hole, the wall of the first mounting hole is provided with a fourth connecting part 315, and the peripheral side wall of the support member 23 is provided with a third connecting part 231. As another example, when the end of the support member 23 is provided with a second mounting hole, the wall of the second mounting hole is provided with a third connecting part 231, and the peripheral side wall of the second mounting part 312 is provided with a fourth connecting part 315.

[0095] The number of third connecting portions 231 can be one or more. Optionally, when there are multiple third connecting portions 231, the multiple third connecting portions 231 are spaced apart along the circumferential direction of the support member 23. Optionally, the distance between two adjacent third connecting portions 231 is equal.

[0096] The number of fourth connecting portions 315 can be one or more. Optionally, when there are multiple fourth connecting portions 315, the multiple fourth connecting portions 315 are spaced apart along the circumferential direction of the second mounting portion 312. Optionally, the distance between two adjacent fourth connecting portions 315 is equal. Optionally, the number of third connecting portions 231 is equal to the number of fourth connecting portions 315.

[0097] When the third connecting part 231 is connected to the fourth connecting part 315, the third connecting part 231 abuts against the fourth connecting part 315, so that the support member 23 is fixed on the second mounting part 312. The connection method between the third connecting part 231 and the fourth connecting part 315 can be a ring snap connection, a cantilever snap connection, a torsion snap connection, a U-shaped snap connection, an interference fit connection, a welding connection, etc., and this embodiment does not limit it.

[0098] In summary, by providing the third connecting part 231 and the fourth connecting part 315, the support member 23 is connected to the second mounting part 312. This not only improves the connection performance between the support member 23 and the second mounting part 312 and enhances the working stability of the sunshade assembly 1, but also facilitates the disassembly and assembly of the support member 23 and the second mounting part 312, thereby reducing installation and maintenance costs.

[0099] In one embodiment, one of the third connecting portion 231 and the fourth connecting portion 315 is a snap-fit ​​protrusion, and the other of the third connecting portion 231 and the fourth connecting portion 315 is a snap-fit ​​groove, the snap-fit ​​groove being used to accommodate at least a portion of the snap-fit ​​protrusion.

[0100] For example, the third connecting portion 231 is a snap-fit ​​protrusion, and the fourth connecting portion 315 is a snap-fit ​​groove; or, the third connecting portion 231 is a snap-fit ​​groove, and the fourth connecting portion 315 is a snap-fit ​​protrusion. Optionally, the shapes of the snap-fit ​​protrusion and the snap-fit ​​groove match, for example, the snap-fit ​​protrusion is a rectangular protrusion, and the snap-fit ​​groove is a rectangular groove. When at least a portion of the snap-fit ​​protrusion is provided within the snap-fit ​​groove, the snap-fit ​​protrusion abuts against the snap-fit ​​groove.

[0101] In summary, this embodiment, by setting the snap-fit ​​protrusion and snap-fit ​​groove, is simple to operate and has low manufacturing cost, and can fix the support member 23 onto the second mounting part 312.

[0102] Please refer to Figures 8 and 9 together. In one embodiment, the end of the support member 23 is provided with a first through hole 232, and the second mounting part 312 is provided with a second through hole 316. The first through hole 232 and the second through hole 316 are used to accommodate the first fixing part 62 so that the support member 23 is fixed to the second mounting part 312.

[0103] The first through hole 232 is provided in a direction perpendicular to the axial direction of the support member 23, and the second through hole 316 is provided in a direction perpendicular to the axial direction of the second mounting member. When the support member 23 is connected to the second mounting part 312, the first through hole 232 corresponds to the second through hole 316. The first fixing part 62 can be a pin, stud, rivet, etc. At least a portion of the first fixing part 62 passes through the first through hole 232 and the second through hole 316 to fix the support member 23 to the second mounting part 312.

[0104] In summary, in this embodiment, after the support member 23 is snapped into the second mounting part 312, the support member 23 and the second mounting part 312 are further fixedly connected through the first fixing part 62, which further firmly fixes the support member 23 to the second mounting part 312, improves the connection performance between the support member 23 and the second mounting part 312, and thus further improves the working stability of the sunshade assembly 1.

[0105] Please refer to Figures 1-14. In one embodiment, the sunshade assembly 1 further includes a spring assembly 40, which includes a spring member 41. The spring member 41 is sleeved on the support member 23, one end of the spring member 41 is fixed to the support member 23, and the other end of the spring member 41 is rotatable relative to the support member 23.

[0106] The winding assembly 20 also includes a tube 42, which is sleeved on the support member 23 and the spring member 41. The other end of the spring member 41 is connected to the tube 42, and the tube 42 is rotatable relative to the support member 23. The outer periphery of the tube 42 is connected to the sunshade curtain 10, and the tube 42 is used to wind up the sunshade curtain 10.

[0107] The spring element 41 has elasticity and can deform. One end of the spring element 41 is fixed to the support element 23, and the other end can rotate relative to the support element 23. Therefore, the spring element 41 can rotate relative to the support element 23 and produce a certain deformation.

[0108] The tube body 42 has a hollow structure and a cavity arranged along the axial direction of the tube body 42. The support member 23 and the spring member 41 are disposed within the cavity. Alternatively, the tube body 42 can be understood as being fitted onto the support member 23 and the spring member 41. The outer periphery of the tube body 42 is connected to the curtain body 102 of the sunshade curtain 10 to facilitate the tube body 42 rolling up the curtain body 102 of the sunshade curtain 10. For example, the curtain body 102 of the sunshade curtain 10 is bonded to the tube body 42. Since the other end of the spring member 41 is connected to the tube body 42, when the spring member 41 deforms, it applies a torque to the tube body 42.

[0109] Specifically, when the spring member 41 rotates relative to the support member 23, the tube body 42 is subjected to torque by rotating the spring member 41 a certain number of turns, so that the curtain body 102 of the sunshade curtain 10 connected to the tube body 42 is always subjected to tension, thereby achieving the effect of tensioning the curtain body 102.

[0110] In summary, by setting the spring assembly 40, the tube 42 used for rolling up the sunshade 10 can achieve the effect of tensioning the sunshade 10, thereby improving the control effect of the sunshade assembly 1 on the sunshade 10 and improving the user experience.

[0111] Please refer to Figures 10 and 11 together. In one embodiment, the spring assembly 40 further includes a spring fixing member 43 sleeved on the support member 23. The spring fixing member 43 connects the other end of the spring member 41 to the tube body 42. The tube body 42 is sleeved with at least a portion of the spring fixing member 43, and the spring fixing member 43 is rotatable relative to the support member 23.

[0112] The spring fixing member 43 has a hollow structure and is sleeved on the support member 23. At least a portion of the spring fixing member 43 is located within the cavity of the tube body 42. This can also be understood as the tube body 42 being fitted with at least a portion of the spring fixing member 43. The connection method between the spring fixing member 43 and the spring member 41, and between the spring fixing member 43 and the tube body 42, can be adhesive connection, threaded connection, snap-fit, etc., and this embodiment does not limit this. For example, the spring fixing member 43 is threadedly connected to the spring member 41, the spring fixing member 43 has external threads, and the spring member 41 is threadedly connected to the external threads. Another example is that the spring fixing member 43 is snap-fit ​​connected to the tube body 42.

[0113] Since the tube 42 and the support member 23 can rotate relative to each other, the spring member 41 can be wound up by rotating the spring fixing member 43. Specifically, when the spring member 41 rotates a certain number of turns, the spring member 41 drives the tube 42 to rotate relative to the support member 23 through the spring fixing member 43, so that the tube 42 is subjected to torque, thereby so that the curtain 102 of the sunshade curtain 10 connected to the tube 42 is always subjected to tension, achieving the effect of tensioning the curtain 102.

[0114] In summary, this embodiment reduces friction between the other end of the spring 41 and the support 23 and the tube 42 by setting the spring fixing member 43, thereby improving the connection performance between the other end of the spring 41 and the support 23 and the tube 42, protecting the spring 41, extending the service life of the spring 41, and improving the working stability of the sunshade assembly 1.

[0115] Please refer to Figure 11. In one embodiment, the spring fixing member 43 is provided with a fifth connecting part 431, and the end of the tube body 42 is provided with a sixth connecting part 421 that cooperates with the fifth connecting part 431. The fifth connecting part 431 is connected to the sixth connecting part 421.

[0116] Furthermore, the fifth connecting part 431 is used to engage the sixth connecting part 421 so that the spring fixing member 43 is engaged with the tube body 42.

[0117] The outer periphery of the spring fixing member 43 is provided with a fifth connecting portion 431, and the number of fifth connecting portions 431 is one or more. Optionally, when there are multiple fifth connecting portions 431, the multiple fifth connecting portions 431 are spaced apart along the circumferential direction of the spring fixing member 43. Optionally, the distance between two adjacent fifth connecting portions 431 is equal.

[0118] The peripheral sidewall of the tube body 42 is provided with a sixth connecting portion 421. More specifically, the inner peripheral sidewall of the tube body 42 is provided with a sixth connecting portion 421. There may be one or more sixth connecting portions 421. Optionally, when there are multiple sixth connecting portions 421, the multiple sixth connecting portions 421 are spaced apart along the circumferential direction of the tube body 42. Optionally, the distance between two adjacent sixth connecting portions 421 is equal. Optionally, the number of fifth connecting portions 431 is equal to the number of sixth connecting portions 421.

[0119] When the fifth connecting part 431 is connected to the sixth connecting part 421, the fifth connecting part 431 abuts against the sixth connecting part 421, so that the spring fixing member 43 is fixed on the tube body 42. The connection method between the fifth connecting part 431 and the sixth connecting part 421 can be a ring snap connection, a cantilever snap connection, a torsion snap connection, a U-shaped snap connection, an interference fit connection, a welding connection, etc., and this embodiment does not limit it.

[0120] In summary, by providing the fifth connecting part 431 and the sixth connecting part 421, this embodiment connects the spring fixing member 43 to the tube body 42, which not only improves the connection performance between the spring fixing member 43 and the tube body 42 and enhances the working stability of the sunshade assembly 1, but also facilitates the disassembly and assembly of the spring fixing member 43 and the tube body 42, thereby reducing installation and maintenance costs.

[0121] In one embodiment, one of the fifth connecting portion 431 and the sixth connecting portion 421 is a snap-fit ​​protrusion, and the other of the fifth connecting portion 431 and the sixth connecting portion 421 is a snap-fit ​​groove, the snap-fit ​​groove being used to accommodate at least a portion of the snap-fit ​​protrusion.

[0122] For example, the fifth connecting portion 431 is a snap-fit ​​protrusion, and the sixth connecting portion 421 is a snap-fit ​​groove; or, the fifth connecting portion 431 is a snap-fit ​​groove, and the sixth connecting portion 421 is a snap-fit ​​protrusion. Optionally, the shapes of the snap-fit ​​protrusion and the snap-fit ​​groove match, for example, the snap-fit ​​protrusion is a rectangular protrusion, and the snap-fit ​​groove is a rectangular groove. When at least a portion of the snap-fit ​​protrusion is provided within the snap-fit ​​groove, the snap-fit ​​protrusion abuts against the snap-fit ​​groove.

[0123] In summary, this embodiment, by setting the snap-fit ​​protrusion and snap-fit ​​groove, is simple to operate and has low manufacturing cost, and can fix the spring fixing member 43 to the tube body 42.

[0124] Please refer to Figures 13 and 14 together. In one embodiment, one end of the spring member 41 is provided with a fixing ring 411, and the support member 23 is provided with a fixing hole 233. The fixing ring 411 and the fixing hole 233 are used to accommodate the second fixing part 63 so that one end of the spring member 41 is fixed to the support member 23.

[0125] The fixing hole 233 penetrates the peripheral sidewall of the support member 23. When one end of the spring member 41 is connected to the support member 23, the fixing ring 411 corresponds to the fixing hole 233. The second fixing part 63 can be a pin, stud, rivet, etc. At least a portion of the second fixing part 63 passes through the fixing ring 411 and the fixing hole 233, so that one end of the spring member 41 is fixed to the support member 23.

[0126] In summary, this embodiment achieves a fixed connection between one end of the spring member 41 and the support member 23 through the second fixing part 63, firmly fixing one end of the spring member 41 to the support member 23, improving the connection performance between the spring member 41 and the support member 23, thereby improving the working stability of the sunshade assembly 1.

[0127] Please refer to Figures 1, 15-16. In one embodiment, the transmission component includes a synchronous belt 22, and the winding assembly 20 further includes two synchronous belts 22 and a second rotating wheel 24. The two synchronous belts 22 are symmetrically arranged on both sides of the support member 23 along their length direction. One end of the sunshade 10 is connected to one synchronous belt 22, and the other end of the sunshade 10 is connected to the other synchronous belt 22. The second rotating wheel 24 is sleeved and connected to the end of the support member 23 away from the drive assembly 30. The second rotating wheel 24 is farther from the drive assembly 30 than the first rotating wheel 21. The first rotating wheel 21 is rotatably connected to one synchronous belt 22, and the second rotating wheel 24 is rotatably connected to the other synchronous belt 22. The reducer 31 drives the other synchronous belt 22 to rotate sequentially through the support member 23 and the second rotating wheel 24.

[0128] The second rotating wheel 24 is positioned away from the drive assembly 30, and the first rotating wheel 21 is fitted onto and connected to the reducer 31 of the drive assembly 30. The second rotating wheel 24 is fitted onto and fixed to one end of the support member 23, and the other end of the support member 23 is connected to the reducer 31. The connection method between the second rotating wheel 24 and the support member 23 can be adhesive connection, threaded connection, snap-fit, etc., and this embodiment does not limit this. Specifically, for the first rotating wheel 21, the reducer 31 can directly drive the first rotating wheel 21 to rotate. For the second rotating wheel 24, the reducer 31 indirectly drives the second rotating wheel 24 to rotate by driving the support member 23 to rotate.

[0129] Furthermore, one synchronous belt 22 is fitted onto the first rotating pulley 21, and the other synchronous belt 22 is fitted onto the second rotating pulley 24. For example, the second rotating pulley 24 is directly rotatably connected to the synchronous belt 22; or, the second rotating pulley 24 is indirectly rotatably connected to the synchronous belt 22 through other components. Optionally, the second rotating pulley 24 has a ring of external teeth, and the synchronous belt 22 is fitted onto the second rotating pulley 24, having a ring of internal teeth, the internal teeth of the synchronous belt 22 meshing with the external teeth of the second rotating pulley 24. In the sunshade 10, one end of the pull rod 101 is connected to one synchronous belt 22, and the other end of the pull rod 101 is connected to another synchronous belt 22.

[0130] In summary, this embodiment simplifies the structure and reduces costs by defining the relationship between the synchronous belt 22, the second rotating wheel 24, the first rotating wheel 21, and the support member 23. This allows the drive assembly 30 to simultaneously drive the two synchronous belts 22 to rotate, thereby driving the sunshade curtain 10 to move and stably roll up the sunshade curtain 10, thus improving the working stability of the sunshade curtain assembly 1.

[0131] Please refer to Figures 1-3 and Figure 17. In one embodiment, the transmission component includes a synchronous belt 22, and the winding assembly 20 further includes a third rotating wheel 25 rotatably connected to the synchronous belt 22. The first rotating wheel 21 and the third rotating wheel 25 are spaced apart along the length direction of the synchronous belt 22. The first rotating wheel 21 drives the third rotating wheel 25 to rotate through the synchronous belt 22.

[0132] The third rotating wheel 25 is rotatably connected to the first rotating wheel 21 by the same synchronous belt 22, and the synchronous belt 22 is fitted onto the first rotating wheel 21 and the third rotating wheel 25. For example, the third rotating wheel 25 is directly rotatably connected to the synchronous belt 22; or, the third rotating wheel 25 is indirectly rotatably connected to the synchronous belt 22 through other components. Optionally, the third rotating wheel 25 has a ring of external teeth, and the synchronous belt 22 is fitted onto the third rotating wheel 25. The synchronous belt 22 has a ring of internal teeth, and the internal teeth of the synchronous belt 22 mesh with the external teeth of the third rotating wheel 25.

[0133] The first rotating wheel 21 drives the third rotating wheel 25 to rotate via the synchronous belt 22. It can also be understood that the first rotating wheel 21 is the driving wheel and the third rotating wheel 25 is the driven wheel. When the first rotating wheel 21 rotates, the first rotating wheel 21 drives the synchronous belt 22 to rotate, and the synchronous belt 22 then drives the third rotating wheel 25 to rotate.

[0134] Specifically, the motor 32 drives the first rotating wheel 21 to rotate, which transmits torsional force to the synchronous belt 22. The synchronous belt 22 drives the third rotating wheel 25 to rotate, thus enabling the synchronous belt 22 to move flexibly in both directions in a circular motion. The slider 27 is connected to the synchronous belt 22, allowing the slider 27 to follow the synchronous belt 22 in a circular motion, thus realizing the forward and backward movement of the slider 27. Furthermore, the slider 27 is inserted into the pull rod 101 of the sunshade 10, enabling the sunshade 10 to move in accordance with the movement of the slider 27.

[0135] In summary, by defining the relationship between the third rotating wheel 25, the first rotating wheel 21, and the synchronous belt 22, this embodiment enables the drive assembly 30 to smoothly drive the winding assembly 20 to move, thereby driving the sunshade curtain 10 to move and stably winding up the sunshade curtain 10, thus improving the working stability of the sunshade curtain assembly 1.

[0136] In another embodiment, the winding assembly 20 further includes a fourth rotating wheel 26 rotatably connected to the timing belt 22, wherein the second rotating wheel 24 and the fourth rotating wheel 26 are spaced apart along the length direction of the timing belt 22; the second rotating wheel 24 drives the fourth rotating wheel 26 to rotate through the timing belt 22.

[0137] At this time, the second rotating wheel 24 and the fourth rotating wheel 26 are rotatably connected to the same synchronous belt 22. The second rotating wheel 24 is the driving wheel and the fourth rotating wheel 26 is the driven wheel. When the second rotating wheel 24 rotates, it drives the synchronous belt 22 to rotate, and the synchronous belt 22 then drives the fourth rotating wheel 26 to rotate.

[0138] In another embodiment, the winding assembly 20 is rotatably connected to the fourth rotating wheel 26 of the timing belt 22, and the second rotating wheel 24 and the fourth rotating wheel 26 are spaced apart along the length of the timing belt 22; the sunshade assembly 1 also includes two drive assemblies 30, one drive assembly 30 is rotatably connected to the fourth rotating wheel 26, and the other drive assembly 30 is rotatably connected to the first rotating wheel 21.

[0139] At this time, both the first rotating wheel 21 and the fourth rotating wheel 26 are driving wheels. The first rotating wheel 21 drives the third rotating wheel 25 to rotate via a synchronous belt 22. The fourth rotating wheel 26 drives the second rotating wheel 24 to rotate via another synchronous belt 22.

[0140] Optionally, the winding assembly 20 further includes a connector 29 disposed opposite to the support member 23, with the third rotating wheel 25 and the fourth rotating wheel 26 respectively sleeved on opposite ends of the connector 29.

[0141] Please refer to Figures 1-3 and Figure 17. In one embodiment, the winding assembly 20 further includes a slider 27 and a guide rail 28 that are slidably connected. The guide rail 28 is arranged along the length direction of the synchronous belt 22. The slider 27 is connected to the pull rod 101 of the sunshade 10 and to the synchronous belt 22. The synchronous belt 22 can drive the sunshade 10 to move through the slider 27.

[0142] The number of guide rails 28 can be one or more. Optionally, the number of guide rails 28 is equal to the number of timing belts 22. Specifically, the take-up assembly 20 includes two guide rails 28 arranged opposite each other, with each guide rail 28 corresponding to a timing belt 22. This can also be understood as one guide rail 28 being adjacent to one timing belt 22. For example, there may be a gap between the guide rails 28 and the timing belts 22; or, the timing belts 22 may be embedded in the guide rails 28.

[0143] The number of sliders 27 can be one or more. Optionally, the number of sliders 27 is equal to the number of guide rails 28, and the number of sliders 27 is equal to the number of timing belts 22. The guide rail 28 has a slide rail, and at least a portion of the slider 27 is disposed within the slide rail, allowing the slider 27 to slide relative to the slide rail. In the sunshade 10, one end of the pull rod 101 is connected to a slider 27, and the other end of the pull rod 101 is connected to another slider 27.

[0144] In summary, this embodiment, by setting the slider 27 and the slide rail, enables the winding assembly 20 to smoothly move the sunshade 10, thereby achieving the winding of the sunshade 10 and improving the working stability of the sunshade assembly 1.

[0145] Please refer to Figures 1-3. In one embodiment, the sunshade assembly 1 further includes a bracket 51 for mounting on the glass assembly. The bracket 51 is provided with a mounting groove 511 for accommodating at least a portion of the drive assembly 30.

[0146] The bracket 51 is used to connect the glass assembly and the drive assembly 30. Specifically, the bracket 51 is connected to the edging of the glass. The motor 32 of the drive assembly 30 is mounted on the bracket 51. Optionally, the bracket 51 is connected to the guide rail 28; or, the bracket 51 and the guide rail 28 are spaced apart. The arrangement direction of the bracket 51 and the guide rail 28 is the same as the length direction of the timing belt 22. The bracket 51 is provided with a mounting groove 511, and at least a portion of the motor 32 of the drive assembly 30 is located in the mounting groove 511. For example, the motor 32 directly abuts against the groove wall of the mounting groove 511; or, the motor 32 indirectly abuts against the groove wall of the mounting groove 511 through other components. The connection method between the motor 32 and the groove wall of the mounting groove 511 can be adhesive connection, threaded connection, snap-fit, etc., and this embodiment does not limit this.

[0147] In summary, by providing the mounting groove 511 in the bracket 51, this embodiment can not only serve as a positioning tool for installing the drive component 30, reducing installation difficulty, but also improve the connection performance between the bracket 51 and the drive component 30, thereby improving the working stability of the sunshade assembly 1.

[0148] Please refer to Figures 1-4 and Figure 18. In one embodiment, the sunshade assembly 1 further includes a locking member 61, which is sleeved on the motor 32. The locking member 61 is threadedly connected to the mounting groove 511 by a fastener, so that the motor 32 is fixed to the bracket 51.

[0149] The locking member 61 abuts against the outer peripheral sidewall of the motor 32. The connection method between the locking member 61 and the motor 32 can be adhesive, threaded, snap-fit, etc., and this embodiment is not limited to any particular method. Specifically, the locking member 61 has a first through hole 212, and the groove wall of the mounting groove 511 has a second through hole 314. When the electrode is mounted on the bracket 51, the first through hole 212 corresponds to the second through hole 314. Fasteners can be pins, studs, rivets, etc. At least a portion of the fastener passes through the first through hole 212 and the second through hole 314 to fix the motor 32 to the bracket 51. In other words, the motor 32 is fixed to the bracket 51 by the locking member 61.

[0150] In summary, this embodiment utilizes the locking component 61 to securely fix the motor 32 to the bracket 51 in a simple and convenient way while ensuring stable operation of the motor 32, thereby improving the connection performance between the motor 32 and the bracket 51 and thus improving the working stability of the sunshade assembly 1.

[0151] Please refer to Figures 4 and 18 together. In one embodiment, the motor 32 includes a first part 321 and a second part 322. The first part 321 is closer to the reducer 31 than the second part 322. The locking member 61 is sleeved on the first part 321 or the second part 322.

[0152] The radial dimension of the first part 321 is equal to the radial dimension of the second part 322. The first part 321 is relatively closer to the reducer 31 than the second part 322. The first part 321 can also be understood as the rear end of the motor 32, and the second part 322 as the front end of the motor 32. Specifically, when the motor 32 is fixed on the bracket 51, the locking member 61 can be located at either the rear end or the front end of the motor 32.

[0153] In summary, this embodiment simplifies the structure and adopts a frameless torque motor, allowing the locking component 61 to be located at any position at the front or rear end of the motor 32, thereby reducing the installation difficulty of the drive assembly 30 and increasing the applicable scenarios of the drive assembly 30.

[0154] This application also provides a glass assembly, which includes glass and a sunshade assembly as described above, wherein the sunshade assembly is fixed to the glass.

[0155] This application also provides a vehicle, the vehicle including a body and a glass assembly as described above, the glass assembly being disposed at an opening in the body.

[0156] The glass assembly and vehicle provided in this embodiment, by adopting the sunshade assembly as described above, align the central axis of the reducer and motor in the drive assembly. This allows the drive assembly to occupy only one direction of the vehicle's space, resulting in a smaller footprint and reduced volume. This further minimizes the space required, facilitating the placement of other components and providing a wider field of vision for the vehicle's sunroof, thus offering more space for the vehicle's sheet metal.
